CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 258,185, dated May 16,1882.

Application filed February 23, 1882. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH DOAN WILsoN,

, self-acting ear-couplings which are adapted to be attached to and usedwith the ordinary linkand-pin draw-heads in common use.

My invention consists principally of suitable collars adapted to beattached to the drawheads by pins passing through the collars and downthrough the ordinary pin-holes in the draw-heads, or by other suitablemeans, the collars being provided with suitable locking devices, andadapted to be rocked or partially rotated upon the draw-heads,preferably by means of shifting or movable counterbalanceweights orpivoted weighted levers for coupling and uncoupling the cars.

My invention also consists of thespecial construction and operation ofthe lockin g devices and of the means for unlocking the same, and

also of the construction, arrangement, and

combination of parts, all as hereinafter fully described.

' Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a plan View of my new and improved car-couplings as theyappear when in locked position. Fig. 2 is a side elevation of the same.Fig.3 is a sectional elevation taken on the line 00 x of Fig. 1, theweighted lever being turned so as to'hold the collar in position forcoupling the cars; and Fig.4 is a sectional elevation taken on the liney y of Fig. 1, the weighted lever being turned so as to hold the collarin position for uncoupling the cars.

AArepresent thecollars, which are attached to the ordinary draw-heads, BB, by the pins 0 G, which pass down through the holes a a and b bin theupper and lower parts of the collars and through the ordinary pin-holesin the draw-heads, as clearly shown in the drawings.

The collars/are formed upon the inside with the projections c c, whichrest upon the drawheads and support the collars, and the holes throughthe collars, through which the pins pass, are elongated laterally, or tothe right and left from the pins, as shown clearly in Fig.

1, to permit the partial rotation or rocking movement of the collarsupon or around the draw-heads for bringing thecollars into position forcoupling and uncoupling the cars. This partial rotation or rockingmovement of the collars is produced by the weighted levers D D, whichare pivoted upon the upper side of the collars to the lugs d d, formedthereon, as shown in the drawings.

The collars are formed with the catches F F, which are upon oppositesides of the collars 6 as thecollars face each other, and the collarsare provided upon the side opposite to that upon which the catches areformed with the pivoted and hooked levers or arms E E, which are held inhorizontal position by the springrods 6 c, and are adapted, when theweighted levers are properly placed for the purpose-- that is, when theyare so placed as to hold the collars square upon the draw-heads, as Ishown in Fig. 3-to automatically drop over the catches F F when the carsare brought together, and thus couple the cars.

To theoutside of the spring-actuated hooked arms E E are pivoted thelevers G G, and in rear of the latches E E are pivoted, to the side ofthe collars, the beveled blocks RE. The levers Gr G are attached to theweighted levers D, between the pivots of the latter and their outerends, by the rodsff, bell-crank levers v I I, and the rods 9 g, asclearly shown in the drawings, and the blocks H H are attached to theweighted levers, below the pivots thereof, by the rods h h, bell-cranklevers J J, and the rods i i, also clearly shown in the drawings. Theforward ends of the levers G G are adept o ed,when the cars are coupled,to rest upon the upper edges of the catches F F, as shown in Figs. 1 and2, and when the weighted levers are thrown over to unlock the hookedarms E E for uncoupling the cars the rear ends of the levers G G will beraised through the medium of their connections with the weighted leversjust described, which will throwthe forward ends of the said leversdownward against the catches F F, and thus serve to raise the hooked Ioo55 I the blocks'L L, which protect the bell-crank arms and insure theirdisengagement from the said catches; and the pivoted blocks H H have anupward movement upon their pivots when the weighted arms are thrown overfor uncoupling the cars, and come against thelower diago' nal faces ofthe hooked arms and serve as additional means for insuring thedisengagement of the hooked arms from the catches. I

In the bottom and to one side of the collars are placed the set-screws kk, bywhich the level of the collars may be adjusted, so that theirmovement upon the draw-heads will not be too great when the weightedlevers are shifted for bringing the collars into position for coupling,but will cause the collars to be held on a level, or nearly on a level,with the draw-heads, as shown in Fig. 3.

To bring the collars into lockin g position the weighted levers must beshifted to the side of the collars opposite to that upon which the setscrews 70 7c are placed. When in this position both collars will be heldsquare upon the drawheads, so that when the cars approach each other thehooked arms will automatically ride over and engage with the catches FF, and thus connect the cars. 7 i

For uncoupling the cars it is only necessary to throw or shift theweighted levers to the opposite side of the collars, which may be donefrom the top or platform of the cars by means of the chains or othersuitable connections,jj,

- and disconnect the cars.

reaching to the top or platforms of the cars, or from the ground betweenthe cars, by throwing or tossing one lever over by hand-and drawing theother over by pulling upon the chain or other connection, which shiftingof the levers will partially rotate, rock, or tilt the collars upon thedraw-heads in opposite directions and bring one ofthem to the positionshown in Fig. 4, which will correspondingly elevate the hooked arms anddepress the catches sufficiently to disengage the arms from the catchesThe action of the levers G G and the pivoted blocks H H will insure andcause the simultaneous disengagement of the hooked arms from thecatches, as above described.

In most instances the collars will be made of such size relative to thesize of the drawheads, and be adapted to such distance of rock ingmovement, that the throwing over of one of the weighted levers will rockor rotate the collar sufficientl y to completely disconnect both hookedarms from the catches.

In front of the bell-crank levers I I are placed I and easily performed,and that the couplings do not interfere with the use of the link and pinfor coupling, in case one of the cars should not be provided with myimproved coupling.

For cars of medium height the collars will have the catches and thehooked arms made upon and attached to them about midway of the sides ofthe collars. For cars lower than the medium height the arms and catcheswill be made and attached higher up upon the collars, and for carshigher than the medium the hooked arms and catches will be made lowerdown on the sides of the collar, so that cars of all heights may becoupled with my improved couplings.

It will be understood that the blocks H H and the levers G G are notindispensably essential to the successful operation of my improvedcouplings, and that they may be omitted, if desired.

It will be noticed that the springs e e, besidesv holding the hookedarms E E, of which they are a rearward extension, in position for engaging with the catches F, are also designed and calculated to supportthe collars and the hooked arms in proper position to meet each otherevenly for coupling.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Paten t, is-

1. In car-couplings, a collar provided with suitable locking devices,and adapted to have a partial rotation or rocking movement upon thedraw-heads, for coupling and uncoupling the cars, substantially asdescribed.
